lb all whom it mag concern:

Be it known that I, LEO F. Ann of Alhany, in the county of Albany and State of New York, have invented ccrtaln new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the -accompanying drawings, forming a part of thls specification, and to the reference-numerals marked thereon;

The present invention relates to eyeglasses of the type in which the guards are mounted to swing on a support by which the lenses are carried, and an object of the invention is to provide a construction and an arrangement of the guard positioning springs that Wlll permit the ,ready attachment and detachment of the guards swings, will render the springs inconspicuous, and at the same time will reduce the friction on and give additional support to the hearings and pivots of the guards.

- To these and other ends the'invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the. claims at the end of the specification! v In the drawings: Figure 1 vis an enlarged front view of apair of eyeglasses embodying this inventio nportions only of the lenses being shown; Fig. 2 is an enlarged detail top view of oneof the guards and portions of the support in proximity thereto; Fig. 3 is an enlarged bottom view of a portion of the'mounting; Fig. 4: is a central transverse section; Fig 5is a transverse section through the support and one of the springs; Fig. 6 is a perspective view of one 'of the guards;

Fig. 7 is a perspective view of a portion of the support; and Fig. 8 isa perspective view of one of the springs.

In the present embodiment of the invention the lenses A are carried by a support which may comprise a bridgmg portion 1 connected to lens attaching devices 2 by a pair of horizontal seats 3. The guards may turn on these seats and comprise levers each made from flat stock extending forwardly and rearwardly of the support. The forwardly extending portion of each guard is bent. vertically transversely of the stock in front of the support to provide a vertically disposed arm 4:, an outwardly extending portion 5 thereon servlng as a finger p ece by which the guard is operated. In rear of the lenses each lever has secured to it anose engaging member which may embody upper and lower pads 6 and 7 respectively;

A pivot pin 8 may connect each guard to the supportand in order to provide ex tended'bearing surfaces each pin maybe carried by a guard and depend therefrom into the support bearing 9. Each guardis positioned by a spring 16 which in this embodiment of the invention is in the form of a coil, arranged on that side of the support opposite the guard, the coil being preferably of volute or flat spiral form and surrounding a pivot pin so that its axis is coincident with the axis of the pin. A projection-10 in the form of a sleeve may be arranged about each pivot pin ,8 in order to prevent friction between the pivot pin and the spring during their operations and at the same timeto provide a support for the'spring when the guard and the support are separated.

To facilitate the removal of the guards,

each spring may have an arm ll detachably interlocked therewith and proceeding for wardly in a horizontal plane from the edge of the stock near the outer end of the spring, a notch 12 being provided in the arm in order to receive a vertical edge ongthe guard which in this instance is formed with a seat 13 on the portion 4 in advance 'oflthe vertical bend. Each spring may be held on the support when its guard is removed and for this purpose another arm l linay be bent or extended horizontally from the edge of the stock near the inner end of the coil to oooperate with the support, the latter being if desirable provided with a seat or book 15 to one side of the sleeve or projection 10and the arm 14 being interlocked with the hook by turning the spring on said sleeve or projection;

i In operation the forwardly extending portions of the guards are pressed toward each other to-separate their nose engaging portions for the purpose of removin or fitting the eyeglasses. On the release 0 the finger pieces the springs move the nose engaging portions toward each other. To detach the guards the arms 11 are moved from their seats 13 and the guards moved vertically to separate their bearings from the hearings on the support. The springs remain on the support until rotated to carry their arms out of engagement with the hooks 15.

j From the foregoing, it will be apparent stability of the .formed and arranged in a that there have been provided eyeglasses in which the bearings of the nose guards are of a maximum length, thus insuring greater parts. The springs are manner to render them inconspicuous while at the same time they give sufiicient power for holding the guards against the nose, and the connect-ion of the springs with the guards and with the support obviates the use of separate fastening devices which increase the size of the mounting and require more labor in assembling. The hearings on the guards and the I anchorage is provided in the support for the pivot pin 8 of the guard whereby no i such looseness can occur as would tend to permit a rocking movement of the lever vertically or in other than its properhorizontal' plane aside from the support afiorded it by the fiat table on which it turns. The seat provided by the flat under surface of the support at the base or attached end of the projection 10 tends to prevent distortion of I the fiat spiral coil in that one side thereof is mediate portions,

- outer convolution of without disturbing other parts disposed toward this seat and its attaching arms are arranged fiatwise against it and the coil and it is particularly desirable that a fiat spiral coil of the type illustrated have some such support as this. centers it by engagement with its interand yet the spring is easily removed in a straight axial direction by simply disengaging its two, free, radially extending arms from their respective seats of the mounting, even the guard which may or may not then be removed, as before pointed out, and on the other hand, by disengaging only the arm 11 from its seat on the guard the latter may be removed without necessarily removing the spring, as it will remain beneath the hooked portion 13 of the projection 9, particularly if it fits closely over the centering project-ion.

The seat 13 on the arm 4 of the guard lever is so constructed as to constitute both upper and lower abutments for the arm 11 of the spring that cooperates therewith inasmuch as, in the present instance, the said arm may not cooperate securely with the seat, on the under side of the support throughout the entire arc of its movement, and the said arm being-extended from the the "spring, which is the least stable, should preferably have an interlocking connection that can hold it in The projection its true horizontal plane of movement. The other arm 14 that runs from the inner convolution across the coil is also supported by direct engagement with the under side of the bridge against deflection in an upward direction, and, therefore, but one abutment, located beneath it as at 15, is sufiicient.

Attention is called to the ease with which this spring may also be applied to the mounting as it is only required that it he slipped over-thefree end of the projection 10 and then momentarily contracted slightly as it is pushed home against its support as the spreading or radial arms 11 and l t'will then automatically spring into their respective seats on the movable and stationary parts. By connecting these arms by bends fiatwise of the stock they are brought as near as possible into the plane of the coil to transmit the action of the latter with greater mechanical economy while the atrial proportions of thespring as a whole are materially decreased. i
